\De*po`lar*i*za"tion\, n. [Cf. F.
d['e]polarisation.]
The act of depriving of polarity, or the result of such
action; reduction to an unpolarized condition.
{Depolarization of light} (Opt.), a change in the plane of
   polarization of rays, especially by a crystalline medium,
   such that the light which had been extinguished by the
   analyzer reappears as if the polarization had been
   anulled. The word is inappropriate, as the ray does not
   return to the unpolarized condition.
